Title: Improvements in or relating to programme control apparatus
Inventor: TWIVEY DERRICK
IPC: G05B19/06
Filed: 1967-10-19
Abstract: 1,237,378. Programmed control. E.M.I. Ltd. Oct.18, 1968 [Oct. 19, 1967], No.47614/67. Heading G3N. An apparatus to be tested is placed on a stand 1 within an environmental test chamber 2 surrounded by heat insulation 3. The temperature in the chamber is maintained and varied with time by the introduction of hot or cold air, via a duct 4 under control of a flap valve, from inlets 8, 7 respectively. The temperature in the chamber is sensed by a device 11 connected to a controller 12 wherein it deflects a stylus 13 carried on an arm 21 over the surface of a rotating table 14. The rotating table is covered with conductive surface 7 constituted by a hard gold-plated coating or comprises a copper laminate. The stylus is provided with an electrical contact, in the form of a phosphor bronze ball or a strip of copper, which is connected by a terminal 15 to an input of a heating controller 20 which is also connected by a terminal 16 to a wiping contact 18. A cam 19 of insulating material, bearing the law of the required variation of temperature of the chamber with time, is fixed to cover part of the surface 17 so that movement of the stylus across the boundary between the conductive and non- conductive zones opens the circuit between contacts 17, 18. The controller responds to the open-circuit by energizing a solenoid 6 which moves the flap valve from its rest position 5, in which cold air is admitted to the chamber, to the position 5<SP>1</SP> at which hot air is admitted. The air in the chamber is stirred by a fan 9 and released through a ventilator 10. The controller 10 comprises a p.n.p. transistor the bias to which is changed by the open-circuiting of the contacts. It is stated that environmental parameters other than temperature can be controlled and that a boundary between dissimilar regions of the rotating table can be sensed capacitively or photoelectrically.

Title: Information storage apparatus and data devices
IPC: G11C19/08
Filed: 1972-10-25
Abstract: 1408442 Recirculating stores WESTERN ELECTRIC CO Inc 25 Oct 1972 [27 Oct 1971] 49171/72 Heading G4C [Also in Division H3] An auxiliary channel 24 (Fig. 2), and a main reoirculating propagating channel L m  are such that data bit propagation occurs in either only the propagating channel or both the auxiliary channel 24 and the propagating channel. Preferably a plurality of minor recirculating channels L 1  .... L n  are arranged to transfer stored data bits to the main propagating channel. MOS or charge coupled reversible shift registers may be used but the particular embodiment is directed to a single wall magnetic domain memory comprising a layer of material in which domains can be moved. When data transferred from the minor channels in response to pulses on conductors 14, 15 is rotated in the clockwise direction in the main channel the data propagates via position 24 from which it can be read out or destroyed by a collapse conductor C and a domain simultaneously generated by a conductor GC. When the data is rotated in the counterclockwise direction the position 24 is bypassed, the bit stored at position 24 being idled. If two bits D 1 , D 2  ; D 3 , D 4 ; ... D n  are transferred from each auxiliary loop to the main loop, any bit D i  may be positioned at the location previously occupied by D 1  by clockwise rotation of the data in the main loop by i steps to bring the bit D; into the position 24. Counterclockwise rotation by i steps followed by clockwise rotation for one cycle brings the bit D i  into the loop in the position previously occupied by D 1 , all the bits D 1  ... D i-1  having been shifted down one position. Counterclockwise rotation of the main loop and return transfer pulses result in the data being returned to the auxiliary loop with D; being stored in the first loop L 1 . This relocation results in recently selected data being located for faster access than other selected data. A plurality of such planes may be employed in a three dimensional memory, the bits of the word occupying similar positions in each plane, some of the bits being used as an address so that a desired word may be selected by magnetostrictive elements S.

The filters are all of similar band width, such as would pass all the channels on the line 10 but one of the oscillators 28, 34, feeding the mixers 26, 32, is adjusted to a frequency such that not all of the signals at its input are passed by the following band pass filter. As described the line carries channels A to G on a frequency band 120 to 162 MHz, which is the pass band of input filter 24. The pass band of filter 30 is 488 to 530 MHz and the output filter 36 a pass band of 174 to 216 MHz, frequencies suitable to feed a conventional receiver. Oscillator 28 is settable to 614 MHz, which will transpose the input frequency band so that only the top channel, channel A, is in the pass band of filter 30, or to 686 MHz, when only the bottom channel channel G will be transposed to the pass band of filter 30, or to 650 MHz when all the channels will be transposed to the pass band of filter 30. Oscillator 34 is set to 704 MHz so that all channels within the passband of filter 30 are transposed to the pass band 174 to 216 MHz of filter 36 and suitable for reception on a standard receiver. Alternatively the oscillator 28 may be fixed at 650 MHz to allow all the channels to pass and oscillator 34 set to restrict the programmes available to the subscriber.
